Acoustic doors?

Albertporter,
Thanks for the advice. I have a contractor that I have been working with and I will talk to him about purchasing and installing the door. It will pobably be few months before the job will be started.
Hopefully I'll remember to post the results.

I would suggest solid core door, not a panel door. Prehung on an exterior frame. Order it without the sill and get a surface mount or recessed automatic door bottom. In addition to the weatherstrip installed in the frame get some surface mounted acoustic seals. Hager hinge makes some stuff at hagerhinge.com . Use 747S or 730S for door bottom and 866 for around frame. This stuff will not be available at home center but is readily available from commercial door suppliers. I used to sell this stuff in another life. Phil Brady.

Thank you Philbrady . This is exactly the kind of information I am seeking. I appreciate what a great resource Audiogon has become for me.
I have learned a lot from this thread and now I can see how mass, stiffness, and air seals all work together to make an effective acoustic door.
In the meantime I am tweaking my layered blanket door cover. It's actually quite nice as it gives the bedroom a cozy yurt-like atmospere that my wife, cat, dog, and I all dig.
